Signals: Think Outside the Event.

Signals are light-weight, strongly-typed AS3 messaging tools.
Wire your application with better APIs and less boilerplate than AS3 Events.

Short Tutorial:

I build some Simple Classes to better understand what you can do with the Signals from Robert Penner

Ok, get startet:

The NativeSignal is Simple easy. I used it to call the onAdded Function.

NativeSignal:

name = new NativeSignal(target, eventClass.constant, eventClass);
name.method(listener);

public function Bubble() {

var addSignal : NativeSignal = new NativeSignal(this, Event.ADDED, Event);
addSignal.addOnce(onAdded);

}

If  you want to have a Mouse Signal just take  a NativeSignal:

private var _mouseSignal : NativeSignal = new NativeSignal(_sprite, MouseEvent.CLICK);
private function onAdded(e : Event) : void

{
_mouseSignal.add(onClicked); // isn´t it easy

}

private function onClicked(e : MouseEvent) : void {
trace("MOUSE Clicked");

}

And for a Custom Signal just take the Signal Class:

Signal:

// A Signal that will dispatch a String and an integer:

progress = new Signal(String, int);

//later:

progress.dispatch(); // will throw ArgumentError

progress.dispatch(‘The Answer’); // will throw ArgumentError

progress.dispatch(‘The Answer’, 42.5); // will throw ArgumentError

progress.dispatch(‘The Answer’, 42); // will succeed

public var _customSignal : Signal = new Signal(String);
private function onClicked(e : MouseEvent) : void {
trace("MOUSE Clicked");
_customSignal.dispatch("Hello from:" + e.currentTarget + " CLASS:" + this);
}

Ok now the Main CLass or we want to listen to the Signals!
Here you have to get the _customSignal and simple add a listner on it

_bubble._customSignal.add(listenToBubble);

public class Main extends Sprite {

private var _bubble : Bubble;
public function Main() {

_bubble = new Bubble();

_bubble._customSignal.add(listenToBubble);

addChild(_bubble);

}

// Receive the value dispatched from the Signal.

// This is like an event handler but without the Event wrapper.

private function listenToBubble(value : String) : void {

trace(value);

trace("Number of Listner:" + _bubble._customSignal.numListeners);

}
}

Ok that ´s all. If you have some questions just feel free to post it here.

private function randRange(minNum:Number, maxNum:Number):Number
 {
 return (Math.floor(Math.random() * (maxNum - minNum + 1)) + minNum);
 }

Sample:
var Count:Number = randRange(0,12);
returns: a Number between 0-12

private function formatNumber(nr : uint) : String {
return (nr < 10) ? "0"+ nr : String(nr);
}

Sample:

var myNumber:String = formatNumber(8);

returns : 08

I found that on Twitter and isn´t it Crazy?

AR.Drone

First quadricopter that can be controlled by an iPhone/iPod Touch/iPad

Thanks to its on-board Wi-Fi system, you can control the Parrot AR.Drone using an iPhone®, iPod Touch®, or an iPad®. It was initially designed for the Apple platforms and will be also available on other platforms in the next few months.

I want to have one …. please Santa C. 

Today i think about the usage from getter / setter or public vars in Classes. First it was to know that you call a Method when you call a setter / getter.

I found on wonderfl a Performance Test and the Result is Amazing!!!

classA use public Vars

classB use setter / getter

object(set only)————————
classA > 311 ms
classB > 636 ms

string(set only)————————
classA > 85 ms
classB > 532 ms

int(set only)————————
classA > 32 ms
classB > 508 ms

object(get only)————————
classA > 29 ms
classB > 450 ms

string(get only)————————
classA > 30 ms
classB > 452 ms

int(get only)————————
classA > 29 ms
classB > 452 ms

object(set/get)————————
classA > 228 ms
classB > 1105 ms
